Salinity is the amount of salt that one thousand grams of water contain. The ocean water has many different amounts of salt mixed in it, or in an oceanography language, different salinities.
Due to the levels of salinity the ocean water has is why humans cannot drink salt water. If a human being (mammals) proceeds with drinking water with high salinity levels, your body will automatically push out those liquids as quickly as possible. Then the human body is programmed to have your kidneys attempt to flush the salts out of your body by urine, and while in the process drain out more water than what you are taking in. After a while one will start to get dehydrated and your cells and organs will not be able to perform their normal functions.
Salinity in Ocean water
The ocean’s salinity averages at about 35 ppt according to “onr.navy.mil/focu s/ocean/ water/salinity1.com”. The salinity of the ocean water can change based on different factors such as rainfall, river runoff, evaporation, and the formation of ice. Marine creatures such as fishes, Crabs, dolphin’s etc. keep the salinity levels inside their bodies at about a similar concentration level as the ocean water does. This way they can survive in such environment. This explains why if you were to place a marine life animal that lives in the ocean (salt water, high levels of salinity) in a fresh water environment like a river or yet worst a fish tank, the animal will most likely not survive. The flow of water rushing through the animal will also highly differ. This process by which water flows through a semi-permeable “membrane” (a material that lets only some things pass through it) such as the animal's skin from an area of high concentration (lots of water, little salt) to an area of low concentration (little water, lots of salt) is called osmosis.( onr.navy.mil/focu s/ocean/ water/salinity1.com)
Salinity In River water
Freshwater salinity on is usually less than 0.5 ppt. Freshwater that are between 0.5 ppt and 17 ppt are called brackish. Estuaries (where fresh river water meets salty ocean water) are examples of brackish waters.( “onr.navy.mil/focu s/ocean/ water/salinity1.com”) Saline flows from the sea at Fremantle due to the tides, and fresh water flows into the estuary from the AvonRiver and other tributaries according to the book.
Due to the fact that large amounts of rain in upstream catchments in winter, a lot of fresh water flows into the River. The flow of the water is so strong that it stop sea water from moving far into the estuary, and therefore making the salinity of the river in winter lot lower than in the summer. This all varies on the season, for example during the beginning of spring the quantity of rainfall decreases and the flow of fresh water that comes into the estuary is seemingly reduced. The ocean water (which has higher salinity levels) moves farther into the estuary with incoming tides.
Salinity in the water of Swamps
The water of swamps is known to be “fresh water”, which basically means ‘water with very low levels of salinity”. Another name used in oceanography language is “brackish water or seawater. The formal definition of a swamp is a wetland that is forested. Swamps are usually more found along large rivers, they are made by natural high tide water levels from rivers that then fluctuate. It is know that All non-tidal freshwater wetlands that have trees, shrubs, emergent’s; and where salinity is below 0.5 ppt their known as swamps. According to (www.americaswetlandresources.com) sometimes their salinity can be near zero PPT (means 0 parts of salt per thousand parts of water; as an example, ocean waters are 35-39 ppt). The types of animals that live in swamps can be divided into various categories, they are basically any animal that requires low levels of oxygen and don’t need high levels of salinity such as fishes, tadpoles and insect larvae.
